Typhoon Opal Route Characteristics
Track and Turning Characteristics
Typhoon Opal (196716) 的生命史长达21天, formed at Northwest Pacific远洋海域 (15°N, 170°E) , 最终在较高纬度消散. 从路径采样数据来看, 其Moving轨迹呈现典型的“W行-NW行-转 toward NE”的抛物线形态. 初期 (8月29日至9月3日) , Typhoon 稳定 toward NW, 纬度从15°N升至20°N, 经度由170°EW进至159.4°E. 9月3日至9月10日期间, 路径逐渐转为N及NNW direction, 纬度快速提升至26.5°N, 经度继续W移.
关键的转 toward 点出现在9月10日至9月12日之间. 9月10日位 at (26.5°N, 139.6°E) , 随后在9月12日到达 (28.4°N, 136.1°E) 后, 路径开始明显 toward E折返. 9月14日坐标变为 (31.8°N, 140.5°E) , 标志着Typhoon 已完成转 toward 并Go to 加速NEMoving阶段. 此后, Typhoon 迅速 toward 高纬度推进, 直至9月19日在 (42°N, 158°E) weakened into Tropical Depression并结束生命史. 整个过程中, 该Typhoon 未Landfall任何land, 始终在洋面上活动.
Intensity evolution and historical comparison
Opal的Intensity演变经历了剧烈的增强与缓慢的减弱过程. formed初期为Tropical Depression, 随后快速加强, at 9月3日达到巅峰状态, 中心最低气压降至919hPa, max wind 达75m/s, 评定为Super Typhoon. 值得注意的是, 在9月5日至9月7日期间, 尽管纬度不断升高, 其Intensity仍维持在Super Typhoon级别 (气压950-960hPa, wind speed55-60m/s) , 显示出极强的生命力. 9月8日后, 随着纬度进一步增加及可能的垂直风切变影响, intensity 开始阶梯式下降, 由Severe Typhoon逐步 weakened into Typhoon , Severe Tropical Storm, 最终在40°N以N的高纬海域消散.
Compared with previous typhoons of the same name, Opal in 1967 was significantly more intense. Its peak pressure of 919hPa was far lower than those of Opal in 1997 (960hPa), Opal in 1973 (968hPa), and the storms of the same name in 1970 and 1976. Opal in 1976 reached only tropical storm intensity, whereas Opal in 1967 reached super typhoon status and maintained high intensity for longer. It was therefore the most destructive in potential and the strongest of the contemporaneous storms sharing this name.

The designation 196716 is the historical identifier used by the CMA for Typhoon Opal, meaning the 16th typhoon of 1967. Its international name was OPAL. The international numbering system for the Northwest Pacific did not begin until 1981; before then, agencies maintained separate numbering systems. The designations assigned by the JMA (Japan), the Joint Typhoon Warning Center of the United States, and China’s meteorological authorities to the same typhoon could differ and cannot be directly matched.
Where did Typhoon Opal's track data come from?
Track data sources: China Meteorological Administration Tropical Cyclone Best Track Dataset (CMA-STI); wind speeds are 2-minute sustained wind speeds.
What is the most powerful Typhoon Opal?
Typhoon Opal peak intensity is Super Typhoon, max wind 75m/s, minimum central pressure 919 hPa.
